SS91BV-M GSM Intercom 10 Revision E15 ,May 2015 Programming Programming can be carried out either by dial into the GSM intercom or by text message (Certain programming feature can only be set up by text message, please refer to user commands P.15) Programming by text message Programming by text message is the simplest way to customize the settings of the GSM intercom and add or delete telephone numbers. Simply send texts in the format to the telephone number of the SIM within the GSM intercom. Note: 1. A Single SMS text messages is limited to 140 characters. 2. You can program many different user command codes in one text message with SMS command format. *12*1234 # [command Code1] # [command Code 2] # [command Code3] #........ 3. Each SMS must start with the pass code , default 1234 in the following format *12*1234 # Followed immediately by a command. 4. To program a call button numbers DO NOT enter country code, just the complete number as you would dial it. Example: Storing a call button phone number (Max 3 numbers) and delete 2&3 phone numbers.(Refer to user commands P.16) 058 57235 (landline number 1) Command to use: *12*1234#1[ Y][ phone number]# 086 5682554 (mobile number 2) 086 2235644 (mobile number 3) Y= number 1, 2 or 3 SMS format: (storing a call button phone numbers) *12*1234#1105857235#120865682554#130862235644# SMS format: (delete 2&3 phone numbers from a call button) *12*1234#12*#13*# User command code CORRECT SMS format: *12*1234#1105857235#120865682554#130862235644# SMS reply: 1105857235#120865682554#130862235644# OK User command code ERROR (user command 19 error) SMS format: *12*1234#1105857235#190865682554#130862235644# SMS reply: 110587235#190865682554# Error SS91BV-M GSM Intercom 11 Revision E15 ,May 2015 Progrmming by dial in Note: programming dial in can’t be used from telephones which are already programmed to open the door when they dial the GSM intercom but you can disable Caller ID display (withhold the number) on the mobile before using. To gain access to the programming mode via dial in, follows these steps: Example: Storing a telephone number for dial in door release Enter Programming Mode by Pressing….. *12*1234# (1234 is default password) A successful pass code will produce a single long beep. A failed attempt will produce 3 short bleeps. You may now program up to 1150 telephone numbers into memory. Use the following commands to program the unit * Insert international country code (1~3 digits): 71 [ country code] # * Add a number (up to 1150 numbers):72 [relay][telephone number] # * Delete a number: 73 [ telephone number ] # * Delete all numbers: 73*# Door /Gate Release (ring in to open) This GSM intercom also has an extra feature to allow user to gain access from their mobile phone by two methods. 1. Caller ID recognition 2. by access control password mode 1. Caller ID recognition to open Ring in to open the door for authorized telephone number. It can support for up to 1150 users. When GSM Intercom receives a call from user, it will check the calling number and if the number is in the list, the GSM Intercom will drop the call and then open the gate / door. The GSM Intercom doesn’t answer the call, it simply checks the caller ID, and so it won’t cost you anything to open the gate / door. SS91BV-M GSM Intercom 12 Revision E15 ,May 2015 For Caller ID recognition to open the door or gate you need to program the mobile numbers and country code into the memory before using. Example: Ireland Country code: 353 (UK: 44 / USA: 1) 086 5683624 (mobile number 1) 086 5682554 (mobile number 2) 086 2235644 (mobile number 3) Command to use: *12*1234#71[country code]#72[relay] phone number] #72[relay][ phone number] #72[relay][ phone number] #....... SMS format: *12*1234#71353#7210865683624#7210865682554#7220862235644# To delete phone numbers of dialing in to open SMS format: (to delete phone number 1 and 2) *12*1234#730865683624#730865682554# SMS format: (to delete all numbers) *12*1234#73*# After the numbers are programmed you can also send the text message to check the stored numbers by sending SMS format *21# , then the GSM intercom will reply the phone number list text message. 2. Access control password to open Dial the SIM card telephone number. The unit will answer the call and you will hear a bleep tone. *33*5678# (trigger relay 1) *34*5678# (hold relay 1) *35*5678# (release relay 1) *36*5678# (trigger relay 2) *37*5678# (hold relay 2) *38*5678# (release relay 2) *Above operation same as sending SMS commands *This is for door open option for telephone numbers not stored. SS91BV-M GSM Intercom 13 Revision E15 ,May 2015 Check GSM signal strength (0~31 levels) When a request for GSM signal strength SMS is sent to the GSM intercom it will reply with a signal strength code and service provider name. The code will be between 0~31 means the signal level is from poor to best. Example: SMS format *20# SMS reply: Vodafone Signal Level = 31 【Signal is very strong】 Check Relay Status You can send SMS command code to check relay status. SMS format *22# SMS Reply Relay=ON Detect = ON【Relay=Hold , Detect=GND】 Remark: Terminal mark” Detect” (see wiring diagram) is for you to connect a door reed switch. The gates would have a reed switch wired through the” DET” input to ground. It’s used by the user to check if the gates are open or closed. Administrator Number Once the administrator number is stored, the unit will only accept programming from this number and only via SMS programming. Example: Program a mobile number as an administrator number via SMS Mobile number: 0865682554 Command to use *12*1234#74 [Admin number]# SMS format *12*1234#740865682554# To delete the Admin number *12*1234#74*# SS91BV-M GSM Intercom 14 Revision E15 ,May 2015 Check A Log Of Dial In And Dial Out Numbers Via E-mail Or SMS This system allows you to save dial in numbers log and will then automatically send the record via e-mail or SMS as your request. There is a list of commands you need and examples to guide you on the settings for this feature. Please setup following required parameters and commands before you can use it. NOTE: G-mail doesn’t support this feature. o. Function SMS command codes *12*1234#83[N]# 1 Auto sending a log of dial in numbers N= 0 (sending when it reaches 100 numbers)- default N=1 (sending when it reaches 200 numbers, Max) Sending record when it reaches 200 numbers. / command code example: *12*1234#831# 2 Way of sending a log of dial in numbers via e-mail or SMS Sending record via email 3 *12*1234#84[N]# N=0 (no saving /sending record) N=1 (via SMS, 4 numbers limited/SMS) N=2 (via E-mail) / command code example: *12*1234#842# GPRS parameters setting *40*1234#APN, auth_type,user name,password# auth_type: 0= none / 1= PAP / 2= CHAP Command code Example: E-mail parameters setting 4 ( Doesn’t support Gmail) *41*1234#SMTP server,port,user name, password, e-mail address, e-mail sender name# Command code Example : 5 Recipient & Carbon copy settings *42*1234# recipient e-mail address, recipient name, carbon copy e-mail address, carbon copy name# Commande code example: SS91BV-M GSM Intercom 15 Revision E15 ,May 2015 No. 6 Function SMS command codes E-mail subject setting *43*1234# e-mail subject# Command code Example: 7 8 To immediately send current dial in numbers log via email or SMS *44*1234# SMS reply: successful or failed *4[N]*1234# N=0 ( reply GPRS parameters) N=1 ( reply e-mail parameters) N=2 ( reply recipient & carbon copy) Check parameters setting N=3 ( reply e-mail subject) Check GPRS parameters setting / Command code example: *40*1234# 9 Mobile number for receiving a log of dial in numbers via SMS *12*1234#85[mobile number.]# 10 Delete mobile number for receiving a log of dial in numbers via SMS *12*1234#85*# 11 SIM phone number used in intercom for Clock date and time correction *12*1234#86[SIM phone number used in the intercom]# 12 To delete SIM phone number used in the intercom for Clock date and time correction *12*1234#86*# Remark: why you need to setup the number for system time clock date and time correction? This device has a time clock and supports automatically updating their date and time via NITZ information from network. In case some of the networks are not available for NITZ information, we strongly suggest to setup this clock date and time correction. When the device detects NITZ information is not available from the network will automatically send a command to itself via the SIM card used in the intercom for time correction which will keep your “ dial in numbers log” with correct date and time. Log Example: I: Dial in number / O: Dial out number SS91BV-M GSM Intercom 16 Revision E15 ,May 2015 How to program checking a log of dial in numbers via SMS There are 3 programming codes you will need to make this feature work You can program many different user command codes in a single text message with SMS command format. *12*1234 # [command Code1] # [command Code 2] # [command Code3] #........

The unit powers up but there is a bleeping from the door station. A. This means the unit is not able to detect the network for some reason. -Check the SIM card is activated and has calling credit. -Power off the unit, remove the SIM and check it in a mobile phone to verify it can make a call. -Check the SIM does not ask for a PIN code when put in a phone. If it does, then disable the PIN code request. -Check the SIM is a standard GSM SIM, not 3G or 4G only SIM. If you are unsure, contact your SIM card provider to verify. Frequency of operation should be any one of the international quad band standards, 850 / 900 / 1800 / 1900 MHz -Check the reception is good. Poor reception is not sufficient. -Check the antenna has been mounted as high as possible, not near large metal objects, or wet green shrubs etc. -Check the antenna connection. Visually inspect that the centre pin inside the antenna is intact, and has not been pushed back inside the fitting. Q. The unit calls the first number, but there is not enough time to answer before it diverts to the next number. A. Increase the no answer time as per programming instructions. Q. The unit calls the first number but voicemail comes on before it can ring the second number. A. Decrease the no answer time as per programming instructions. Q. The caller ID part does not work. A. Be sure to program the caller ID part under 72 feature. If your number is a private or number withheld, then it will not work. Even if you have already programmed a number to receive a call from the intercom, if you also want that number to have caller ID access, it must be programmed under the 72 feature also. Ensure the number is entered as you would normally dial it from another phone. Q. There is no audio from the gate, but the person at the gate can hear ok. A. This can be due to low reception. -Check reception level by *20#. -Change SIM card if necessary to another network which may have better coverage. -Purchase a high gain antenna. SS91BV-M GSM Intercom 23 Revision E15 ,May 2015 Q. The audio quality that can be heard on the remote telephone is poor or humming (buzzing). A. A small amount of GSM buzz can be considered normal on GSM intercoms, but not so much that causes inability to hear the person speaking. This can be caused by the GSM antenna being mounted too close to the speech panel or not mounted high enough. -Try earthling the speech panel chassis to 0V of the power supply. -This is also a symptom of poor reception. Try above steps on checking and improving reception. Q. The * or # key does not work when the intercom calls a phone. A. Check if you can hear the relay clicking at the gate when the * or # key is pressed during a call. If it can be heard, then the system is working, check wiring between the relay and the lock or gate panel. If the relays do not make a clicking sound, then check this feature on a different mobile cell phone or landline. If it works on a different phone, check the settings on the phone in question under DTMF tones. Failure of DTMF tones to operate correctly is also a symptom of low reception. Check steps above on improving reception. Try pressing the buttons longer when attempting to activate the gates or door.
